ABSTRACT:
In one embodiment, the invention is an apparatus. The apparatus includes a framer to receive packets, to determine a type associated with received packets, to pass data packets to a network processor, and to pass control packets to a host processor. The apparatus also includes a processor coupled to the framer to control the framer.
